Current LIT implementation uses dst components for storing temp results, possibly overwriting still needed values (depends on the swizzles). This patch uses temp reg for one of such cases (found in etqw) and fixes "LIT R.z, R.xyzz". Tested on evergreen. Fixes some etqw-demo rendering glitches when "Lighting" is set to "High" in the settings. Signed-off-by: Vadim Girlin <vadimgirlin@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
